Title: Improvements in or relating to sewing machines
IPC: D05B35/06
Filed: 1954-03-26
Abstract: 803,699. Sewing machines. UPRICHARD, W. H. May 20, 1955 [March 26, 1954], No. 8839/54. Class 112 Starting and stopping gear. In a sewing machine adapted for hemming long lengths of material and provided with driveinterrupting means comprising a feeder device resiliently biased into engagement with the stitching or with the turned over edge of the hem rearwardly of the stitching position, a solenoid is adapted to be energized by the operation of electrical contacts associated with the feeler device, and a friction clutch is spring-loaded to the inoperative position but is held in the operative position by catch means adapted to be released on energization of the solenoid. A further feeler device, normally resting on the edge of the material passing over the guide bar, is adapted to contact said bar to energize the solenoid if the material becomes misaligned relatively to the hem-forming means. The machine is driven by a continuous belt 12 which passes over the driven pulley 33 of an electric motor 11, a pulley 14 and the driving pulley of the machine. The material 34 passes through tensioning means 35x and then over a guide bar 35 to hemforming means 36 before passing to the sewing position n. The edge of the stitched hem 21 is engaged in the rear of the latter by a blade 20 carried by a spring arm 19, movement of which, on failure of the stitching, serving to close an electric switch 22 whereby to energize a solenoid 30. The armature 29 of the latter is pivoted to the free end of a lever 27 carrying a bar 26 formed with a catch element which, when the machine is operating normally, overlies a catch element on a bar 25. The latter is carried by an arm 24 adapted to operate a clutch 23 for driving the pulley 33. On energization of solenoid 30, lever 27 moves anti-clockwise, whereby the catch elements are disengaged to allow a spring 31 to move the clutch to the inoperative position. The clutch is restored to the operative position by means of a treadle connected by a rod 32 to arm 24. Mounted on bar 35 is bracket 39 on which are pivoted at 38 three fingers 37 having pointed free ends which rest by gravity upon the selvedge of the material passing over bar 35. Wandering of the material will serve to allow one or more of said fingers to contact bar 35 for closing an electric circuit to energize the driveinterrupting solenoid 30. Feeding. The hemmed material is drawn off by a pair of variable speed rollers 16<SP>1</SP>, 17 the latter of which is driven by reduction gearing 18 from a shaft 16 carrying a friction wheel 15 movable along shaft 16 to contact the friction face 14a of the driven pulley 14 at variable distances from the axis of the latter.

Title: Improved control for stokers for solid fuel combustion apparatus
Inventor: DRIVER FREDERICK ARTHUR
IPC: F23N1/02
Filed: 1964-03-03
Abstract: 1,061,611. Feeding fuel and air to furnaces. JOSHUA BIGWOOD & SON Ltd. May 24, 1965 [March 3, 1964], No. 8851/64. Heading F4B. The automatic fuel feed to a furnace is driven by a motor driving the forced draught fan directly, through a transmission including a timer controlled electromagnetic device operating so as to render the transmission effective only a predetermined time after the fan motor has started, and rendering the transmission ineffective a predetermined time before the fan motor is stopped. The transmission from the fan motor is of the intermittent friction type described in Specification 486,722, and the electromagnetic device operates to hold off a brake shoe preventing the return motion of an oscillating wheel driving the stoker. The timer controls switch circuits so that, for a short time after the fan motor is started, the stoker driving wheel oscillates without driving the stoker, the electromagnetic device is then de-energized and the stoker is driven step-by-step. Similarly, when the air/fuel supply is switched off, the electromagnetic device is energized to prevent the stoker being driven for a short period before the fan-motor is switched off.

As shown, a four-wheeled bogie for a motor road vehicle comprisesa bracket 10 secured to each side frame 9 of the vehicle and supporting a cross member 11 which carries near each bracket 10 pair of pillars 12 to which a platform 13 is rigidly attached. -The platform 13 bears on a bottom plate of a hollow beam 20 through rubber blocks 21. The pillars 12 pass through slots on the bottom plate of the beam 20 to permit longitudinal movement of the beam, the blocks 21 then acting in shear. Combined shear and compression springs 16 are disposed between the ends of the beam 20 and axle brackets 15. The axles are connected to the cross member 11 by lower pivoted links 23 and to frame members 9, by upper pivoted links 24. A Panhard rod extends between each axle and the member 11. The arrangement is such that load on one wheel is transmitted through its associated spring. 16 with consequent longitudinal movement of the beam 20, to the spring associated with the other wheel to equalize the load on both wheels. The links 23, 24 may be replaced by a pair of vertically-spaced parallel links for each axle at each side of the frame and the Panhard rods may be replaced by a V- shaped link which replaces one of the links 23, 24. The blocks 21 may be replaced by pivoted links acting in tension or compression, the angularity of the links determining the spring characteristics. The invention is applicable to rail bogies. Specifications 648,516 and 716,563 [both in Group XXXII] are referred to.

Abstract: 114,083. Wyatt, H. E. June 30, 1917. Maps; models. - A map or the like is mounted on mill-board, wood, or other material, and is cut along the contour lines 1, 2, 3, 4, Fig. 1. The part representing the lowest level is mounted on a base, and the inner space is filled with material such as clay. The section 1 is then placed in position and filled up to support section 2, and so on, to build up the mould, as shown in Fig. 2. In an alternative method, the filling material is dispensed with, and three copies of the map are cut up, one on every contour line, and the other two on alternate lines only. The model is then built up as shown in Fig. 6, in which the sections I, III are cut from one map and the sections II, IV from another. The sheets from which the supporting sections are cut are preferably thinner than the sheet from which the section 1, 2, 3, 4 are made. When the mould has been built up in steps, the angles may be filled in with modelling clay to the points A, B, C, D, or the edges may be cut back to the inner points a, b, c, d. Finally, the model may be covered with cloth, paper &c. having the map printed on it.
